Line for the server...

Everything rides on how many values you want to save. If you want just one,
save it to a -local-

webuse lbw2, clear
logistic low age lwt race2 race3 smoke ptl ht ui, vce(bootstrap, reps(100))

If you want to do this repeatedly, you might want to look into -postfile-...

Subject: st: saving bootstrapped ROCs

I'd like to save the ROC values from bootstrapped logistic regression
equations.  I can bootstrap the logistic regression command, but I'm not
sure how to capture the ROCs, since the ROC is computed using a command that
follows the -logisitic- command., e.g.,

.logistic <vars>
.lroc

Any suggestions?

 Thanks,
